Term for a band/group that has one breakthrough hit that people remember after usually years of making underground music. They may try to luanch more chart-friendly songs on the back of their one song that will fail to have any impact. Will fade back into obscurity within a month only appearing for the odd television appearance.

The ultimate one hit wonder were Los del rio who inspired a massively popular dance to go with their catchy song; La macarena!

Los del rio were making music for over 20 years before La macarena became a hit.

1)a band that has had only (I shouldn't say only, since most bands never have a successful song) one song that was a commercial sucess.
2)A song which was the only success of the band that played it.
3)A strain of marajuanna grow in Southern California (San Diego's north county) which is so potent that one hit will get you more high than you have ever been before.

1.a band, while during any time in their existance, has only one song achieve the 'hit' status. after which, they fizzle out and disappear, never following up their initial success
2.(lesser used def.)a girl/guy, who is not sexually desirable, but gets a piece of your ass via intoxication, low light, etc.

1.the Crash Test Dummies were a one-hit wonder.
2. Man, why'd you grind that chick? She was fuckin ugly! Yeah, it was a one-hit wonder.

A band or singer that everyone forgets about after their hit song runs its natural course into obscurity, because they can never get back onto the charts again. Most one-hit-wonders are that way because either they can't write their own songs, or their own songs are crap.

Crossover songs and artists are sometimes mistaken for One-Hit-Wonders, because listeners outside their genre don't know who they are. Anyone unfortunate enough to make this mistake is likely to be taken to task by numerous members of the artist's following, because it takes quite a good artist to pull off a crossover hit.

Your own songs just aren't going to cut it. Go find a hit song that no one else has covered in at least 20 years, so the teen audience will think it's new, and maybe you can be a One-hit-wonder.
